Puzzles of Finance: Six Practical Problems and Their Remarkable Solutions by Mark P. Kritzman (2002)
The first one is "Siegel's Paradox", which seem to be basically a prolonged discussion around the fat that losing 50% of your investment means that you need to make 100% to get back to where you started, expressed in the terms of foreign exchange rate moves (or I might have just missed something on this one). But of course, the actual purchasing parity moves the opposite direction, so there is no free lunch to have based on exchange rate movements.
The next chapter discusses, how the likelihood of loss can be about anything, depending on how exactly the criteria is spelled out.
Chapter 3 on time diversification discusses if/how the investment time horizon effects risk (this is dependent on how we defined risk) and the surprising answer might be, that longer term investing carries the same risk as shorter term (in particular if risk is measured in using log wealth utility function). The log wealth utility function (first expressed in Daniel Bernoulli's St. Petersburg Paradox, the Bernoullis also had a major role in defining
Chapter 4 demonstrates, using bootstrapping (which is resampling of the results of a past period repeatedly) of real returns on securities, that geometric average/mean of a compounding distribution is higher than its median, so your expected return on your investment is not to be expected. Chapter 4 also demonstrates the asymetricity in compounding effects of geometric returns, where the high end of returns are further away from the middle value, than the low end of returns (both in percentage and actual values). At the same time, the percentage of continuous returns stays symmetrical.
The next chapter offers the view, that an investor is better off using a balanced strategy (investing in a riskless and risky asset at the same time), as contrasted to switching between those same assets for equal periods. While the cumulative wealth are the same, the switching strategy has higher variance (it is riskier). To arrive to the same Sharpe ratio (as expressed by dividing the excess return of an investment by the standard deviation of that same excess return), the switching 100% each year strategy would need to bring an extra 5% of return (this is the market timing skill needed to make switching worthwhile). These results are even more pronounced if log wealth utility is applied to these returns. Another demonstration of increasing risk for longer timeframe is shown by option pricing, prices for options increases with volatility, but it also increases with longer expiration (even if volatility stays the same).
Chapter 6 explains how the pricing of options is independent from the expected return of the underlier. The Black-Scholes formula indeed has no reference to the expected return (although one probably should argue that volatility, which is assumed to be known and constant by the formula is greatly influenced by the changing perceptions and expectations of the expected return), instead the riskless return determines the option price (based on equivalence of hedged positions). Volatility of an asset can be expressed using beta, which represents the asset's non-diversifiable risk (which relates the return of the asset to the market's expected return). The chapter offers a good history of the formula from botany, through heat distribution to corporate finance. The law of one price is also related, stating that price of assets is independent of the capital structure and dividend payment policies.
Good brainteasers.

Our Brave New World by GaveKal Research (2005)
There is also the giant sloshing pool of capital invested with the various hedge funds, trying to find inefficiencies (and quickly eliminating any and all), working with leveraged "return to mean", "momentum based" and "carry trade" strategies. Lots of capital chasing less opportunities, so capital is becoming cheaper, but mostly for the customer in the developed countries (as platform companies need less capital, and it is likely not smart to lend to the volatile industrial producers and to their workers, who can get laid off very quickly ...) moving us towards a deflationary environment.
So where does this lead us? The conclusion on the decreased volatility and sustainable real-estate prices were incorrect conclusions, based on the latest dips (or depression ...) in the US Housing prices and great increase in the market volatility. Maybe this was just another asset bubble (sustained by the extra low US interest rate) or the world economies need to be observed as a whole. Also the deflationary pressure seem to be lacking just by looking at the US budget deficit. But there are other valuable pointers: invest in customer related companies (retail, finance, although finance stocks are not doing that great either), buy scarcity assets (like high end real-estate, art, and the like), invest in emerging markets (with an eye on the economy cycles) and invest in platform companies everywhere. There is also an interesting table evaluating various economies, on how much Ricardian growth (based on economic freedom) and Schumpeterian growth (based on economic creativity) is expected to happen (the UK and Eastern Europe do quite well, the US and Australia lining up behind). Recommended.

Full of Bull: Do What Wall Street Does, Not What It Says, To Make Money in the Market by Stephen T. McClellan (2007)
- deletion of stock coverage is a major read flag (this happens in lieu of downgrading)
- there is a large company bias, and small companies are rarely covered (this also shows that this research is oriented towards institutional investors)
- executives never think that their stock price is too high
- executives and hedge funds curry, cajole and muscle favors with analysts (and the companies employing them). Major PGA golfing events definitely come to mind here ...
- prefer specialized simple businesses (as compared to generalist companies)
- avoid weird tock structures (voting, non-voting shares), and sweetheart management setups
- invest in themes and rising industry sectors (maybe using ETFs)
- prefer NYSE listed stocks to NASDAQ
- tread lightly with International Companies
- turnarounds almost never work
- do not invest in IPOs
- mutual funds offer safety bundled with mediocrity
- (for US investors) focus on the one year mark (for reduced capital tax rates)
- do not sell on downgrade (in particular on the day of a downgrade), the stock price likely has already fallen
- be aware of the January effect, as January goes, so goes the whole year
- do not read quarterly press releases, but do listen to the quarterly earnings conference calls
- investigate hedge fund positions (if they happen to be accidentally revealed), but give little head to mutual fund positions (as they get paid by the size of the fund, not based on their performance)
- give stocks to your kids
- dramatic acquisition during troubled times is a diversionary tactic
- stock buybacks usually do not accomplish much
